\"\"<\/a>Many thanks to SWLing Post<\/em> contributor, Giuseppe Morl\u00e8 (IZ0GZW)<\/a>, who shares the following:<\/p>\n

Dear Thomas my<\/strong> friend,<\/strong><\/p>\n

I built another Tferrite, (TFERRITE 2), for medium waves–this time also with the shortwave option.<\/strong><\/p>\n

A single variable capacitor, 800 pf, and a primary winding on the 2 ferrites of about 46 turns, a secondary winding of 3 turns to pick up the signal and send it to the receiver.<\/strong><\/p>\n

On the PVC tube I wound 4 more coils, for the shortwaves, connecting the ends to the same variable together with the other ends.<\/strong><\/p>\n

I interposed a switch on one end to eliminate or insert shortwaves.<\/strong><\/p>\n

I am sending you these 3 links from my YT channel where you can see the tests I have done in these days with no propagation.<\/strong><\/p>\n

The yield in mediumwave is excellent, like the other one<\/a>, yet also good for the shortwaves–to be so small it compares very well.<\/strong><\/p>\n

Let me know what you and the whole SWLing community think!<\/strong><\/p>\n

Thanks to you and a greeting from Italy, Formia on the Tyrrhenian Sea.<\/strong>
\n73. Giuseppe.<\/strong><\/p>\n
